6 October 2012 - added Tamura's matrices and their Gram matrices in
sizes 35, 39, 43, and 63 to their respective pages.

6 October 2012 - added two successive improvements in size 45 due to
[BOOZ] using doubly-three-normalized constructions.

5 October 2012 - added records in sizes 78 and 94 found by Rokicki following
Lars Backstrom's programming contest back in 2005.

3 October 2012 - added record in size 70 found by Orrick and Rokicki following
Lars Backstrom's programming contest back in 2005.

2 October 2012 - added four new records from Hiroki Tamura to table
in sizes 35, 39, 43, and 63. Record matrices and their Gram matrices,
which have Ehlich block form, have not yet been added to the pages for
the corresponding n.

30 August 2012 - removed statement in key about
exceptions to the factorization rule used in the table, since it was no
longer relevant. (Thanks to Richard Brent.)

30 August 2012 - corrected statement for n=19 that incorrectly stated
that M1 and M2 had not been proved to be the only
maximal forms. (Thanks to Richard Brent for this correction.)

30 August 2012 - added reference to Djokovic and Kotsireas's construction
of D-optimal designs of orders 206, 242, 262, and 482 to the
bounds page and to the bibliography
([DK]. (Thanks to Ilias Kotsireas.)

20 December 2011 - noted that the designs for n=19 and n=37 have been proved
maximal [BOOZ] and the three designs
for n=19 have been shown to be a complete set.

27 August 2005 - added new record in order 59,
two-circulant construction discovered by Tomas Rokicki and independently
found by Ivan Kazmenko and Vadim Trofimov.

27 August 2005 - added new record in order 55,
two-circulant construction discovered by Tomas Rokicki and independently
found by Ivan Kazmenko and Vadim Trofimov and by Jean-Charles Meyrignac
and Jaroslaw Wroblewski.

26 April 2005 - added new record in order 51,
two-circulant construction discovered by Tomas Rokicki and independently
found by Ivan Kazmenko and Vadim Trofimov and by Jean-Charles Meyrignac
and Jaroslaw Wroblewski.

25 April 2005 - added new record in order 43,
two-circulant construction discovered by Tomas Rokicki and independently
found by Ivan Kazmenko and Vadim Trofimov and by Jean-Charles Meyrignac
and Jaroslaw Wroblewski.

24 April 2005 - updated values of determinants found by Tomas
Rokicki in orders 105 and 109.

22 April 2005 - added new record in order 85,
discovered by Will Orrick and Bruce Solomon on December 8, 2003.

21 April 2005 - added new record in order 57,
discovered by Jean-Charles Meyrignac by hill climbing from a matrix
constructed by Bertram Felgenhauer during the Lars' programming contest.

19 April 2005 - added new record in order 35,
two-circulant construction discovered by Tomas Rokicki and independently
found by Ivan Kazmenko and Vadim Trofimov and by Jean-Charles Meyrignac
and Jaroslaw Wroblewski.

14 April 2005 - extended table to include Hadamard matrix in order
116, D-optimal design in
order 118 (Fletcher, Koukouvinos, and Seberry), and
new records found by Tomas Rokicki in orders
117 and 119. Since the latter are still in daily
flux, only stub pages were created.

12 April 2005 - extended table to include Hadamard matrices in orders
104, 108, and
112, Brouwer design in order
113, D-optimal designs in
orders 110 (Fletcher and Seberry) and
114 (Koukouvinos, Kounias, and Seberry), and
new records found by Tomas Rokicki in orders
105, 106, 107, 109, 111, and 115. Since the latter are still in daily
flux, only stub pages were created.

8 April 2005 - added new record in order 78,
Ehlich-type construction with circulant blocks discovered by Tomas
Rokicki

7 April 2005 - added new record in order 58,
Ehlich-type construction with circulant blocks discovered by Tomas
Rokicki and independently by Ivan Kazmenko and Vadim Trofimov
